This invention relates to a machine for rupturing the ends of wire projecting from heedles made of wire and more particularly from twisted vwire heddles.

According to the invention, the ends to be ruptured are given a number of successive leXions, by means of moving guides whereby rupture, occurs just at the end of the twist.

The guides may be reciprocated or rotated;

they may be in the form of forks or bars.

The annexed drawing diagrammatically shows a machine according to this invention.

Fig. l is a plan view with broken parts.

Fig. 2 is a section on line II-II (Fig. 1).`

F ig.f3 represents to anenlarged scale an heddle and the set'of bars.

The machine comprises a table 1 supporting two triangular frames 2 on which rests the rotatable shait 3. l f

A cable 13 is attached to one arm 11; this h cable passes over idlers 14 and 15 and supports a counterweight 16 which thus tends to rock the arm 11 and to 'lift the bar 12.

A lever 17 is pivoted on each arm 4. Each lever 17 `is provided with a groove 18 (Fig. 2) 3,5which may cooperate with a stud 19 fixed to the corresponding arm 11. When the two levers 17 are thus in engagement with the two studs 19, arms 11 and 4 are locked together.v

Shaft 3 also loosely supports two levers 20 each one being provided'at one end with a Vcounterweight 21, 1whilst the other end is pivotally connected with a rod 22. The two. rods22 support ka bar 23. Y

' The frameworks 2 rotatably support a i 5 Shaft 24 lprovided with an actuating lever25 Two depending arms 4are keyed on shaft theother one being free andsupported only by the heddles themselves, and the projecting and with two cams 26 which may cooperate with levers 20 in order to rock the same and thus press bar 23 table 1.l

A bar28 is placed between bars 5 and. 12. It is iixed by means oftwo stays -29 Awhich are provided with notches 30 cooperating with studs 31 fixed onbars 5 and 12 and provided with iy-nuts or the like.

Table 1 also supports -a bar 32 its ends, with hooks 33 (Fig. 2).

The operation isasfollows: v The parts being in the position shown, bar 28 is removed and levers 17 are lifted by hand; arms 11 and` bar 12 are thus freed and rocked by counterweights 16. Bar 12 contacts with rods 22 and` drives the same. The parts thus assume the position shown in `dotand-dash lines,`Fig. 2.

The heddles 34 are preferably maintained by means of two rods or shafts 35 which are passed through vtheir end rings (Fig. They are disposed as shown in the drawings, one of rods 35 being engaged into hooks 33 aga-inst a bar 27 resting on ends 36 to be ruptured being inthe neighbourhood ofbar.. v y Y Arms 11 are then lowered and locked by means of levers 17 (position represented in full lines). Rods 22 thus re-assume thei vertical position.

Lever 25 islowered and'bar 23A is thusv Y l pressed against bar 27, the heddles 34 being" firmly maintained between the said bars.

Bar 28 is then placed .between bars 5 and 12. As clearly shown, Fig. 3, the arrangef ment is such that the ends 36 to` be ruptured are located between bars 12 and 28 or be-4 tween bars 28 and 5. 1

' The motor 8 is started and it reciprocates the three bars 5 12 and 28 as a whole. The Y ends 36 are thus submitted to a number of suc, cessive exions which rapidly cause their rupture exactly at the end of the twist. 1 o
